The aim of this study was to examine driving exposure, habits and harsh braking events in older drivers with bilateral cataract using naturalistic driving data.

A multiple linear regression model was undertaken to examine predictors of driving exposure in older drivers with bilateral cataract. After controlling for potential confounding factors, only binocular contrast sensitivity (p
